This announcement constitutes a Broad Agency Announcement (BAA) for the Naval Facilities Engineering and Expeditionary Warfare Center (NAVFAC EXWC) under FAR 6.102(d)(2) and FAR 35.016. This announcement is open for one year and will be advertised annually. NAVFAC EXWC provides research, development, testing, and evaluation (RDT&E) to deliver specialized facility, ocean system, and expeditionary solutions to the warfighter. To be eligible for consideration and possible contract award, the technology or methodology shall be in either applied research (Category 6.2), advanced technology development (Category 6.3), or advanced component development and prototypes (Category 6.4) (https://www.dau.edu/glossary/research-development-test-and-evaluation-budget-activities). Furthermore, the technology or methodology shall address one of the following topic areas that advance Naval capabilities: Topic 1 – Expeditionary Construction, Battle Damage Repair, and Advance Naval Base Construction Technologies This area prioritizes technologies that enable rapid and effective construction, repair, and development of infrastructure in austere, contested, or damaged environments. Core interests span lightweight, multi-functional, and adaptable equipment suitable for diverse terrains; advanced construction and repair materials for rapid deployment and restoration; and automated or robotic systems to enhance speed and efficiency. Crucial enablers include precise site/damage assessment tools, modular and scalable structures and repair systems, efficient techniques for site preparation and stabilization, and mobile, self-sufficient solutions with a minimal logistical footprint to support expeditionary operations. Topic 2 – Logistics Over the Shore Technologies This area focuses on technologies that enable the rapid and sustained transfer of personnel, equipment, and supplies from ship to shore, particularly in austere or contested environments where traditional port infrastructure is limited or unavailable. Core interests include advanced amphibious connector craft and lighterage systems; modular and rapidly deployable causeways and piers; and automated cargo handling and transfer solutions that minimize beach time and maximize throughput. Critical supporting technologies encompass mobile fuel and water distribution systems, all-terrain material handling equipment, real-time tracking and visibility of cargo to ensure uninterrupted logistical operations. Topic 3 – Waterfront Facilities and Systems Technologies that advance and sustain waterfront facilities in the harsh marine environment in the areas of cathodic protection, corrosion and weathering, metallurgy, concrete and pavements, and paints and coatings. Special areas of interest include adaptation of dry-docks and harbor facilities to ensure resilience when exposed to extreme weather events; technologies that improve inspections for pier, wharf, water and fuel tanks, dams, and bridges; and developments in marine and…
